Forcameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus. " Acceptably sharp focus" is defined using a property called the "circle of confusion".The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture.

Judul Tentang Depth of Field DOF Dalam Fotografi BELAJAR FOTOGRAFIlink Tentang Depth of Field DOF Dalam Fotografi BELAJAR FOTOGRAFI Tentang Depth of Field DOF Dalam Fotografi BELAJAR FOTOGRAFI Depth of Field DOF atau ruang ketajaman atau kedalaman ruang adalah penjelasan tentang seberapa luas area yang tajam dan area yang tidak tajam blur pada sebuah gambar. Dalam artikel ini kita akan membahas seperti apa itu yang dimaksud ruang ketajaman dan faktor yang mempengaruhi terjadinya DOF lebar maupun DOF sempit. Pada gambar pertama di atas area yang tajam terletak pada subjek patung utamanya kepala dan sedikit area duduk patung, selain dari itu semua area dalam frame tampak blur. Nah, seberapa luas area yang tajam dan seberapa luas area yang blur pada gambar di atas itulah inti pembahasan dari depth of field. Sedangkan arti kata "tajam" di sini adalah bagian dari gambar yang detailnya jelas terlihat dan tidak mengalami blur. Depth of field ini berprioritas pada seberapa luas area yang tajam pada gambar dan menyisakan bagian yang tidak tajam blur. Dan juga menjadi salah satu variabel yang ikut mendukung intensitas blur pada background. Perbedaan DOF Lebar & DOF Sempit DOF yang lebar dan DOF yang sempit adalah tidak lain merupakan luas dan sempitnya area yang tajam pada gambar. Jadi ketika area yang tajam lebih luas ketimbang area yang blur maka ia dikatakan sebagai DOF lebar, begitupula sebaliknya. Mudah dipahami kan? Contohnya seperti subjek patung di atas, yang karena area yang tajam tidak begitu luas yaitu hanya pada subjek patung khususnya area kepala dan sedikit area duduk patung, sedangkan area yang blur lebih luas sehingga foto di atas dikategorikan sebagai DOF sempit. Sedangkan contoh sederhana untuk DOF lebar coba Anda perhatikan sebuah foto yang diambil menggunakan kamera ponsel. Pada umumnya foto yang dihasilkan oleh kamera ponsel adalah DOF lebar yang dimana hampir semua bagian foto tampak jelas, bahkan mungkin Anda pernah melihat tidak ada satu bagianpun dari gambar yang mengalami blur. Faktor Terbentuknya Depth of Field Faktor utama yang mempengaruhi depth of field ini adalah bukaan lensa yang juga disebut sebagai aperture atau diafragma. Jadi, kunci untuk memberlakukan "seberapa luas area tajam" yang akan terjadi pada gambar adalah tergantung dari penggunaan aperture atau difragma lensa. Teorinya yaitu semakin lebar bukaan aperture yang digunakan maka semakin sempit area tajam pada gambar, begitupula sebaliknya. Selamat belajar!! Demikianlah Artikel Tentang Depth of Field DOF Dalam Fotografi BELAJAR FOTOGRAFISekianlah artikel Tentang Depth of Field DOF Dalam Fotografi BELAJAR FOTOGRAFI kali ini, mudah-mudahan bisa memberi manfaat untuk anda semua. baiklah, Karena keterbatasan pengetahuan maupun pengalaman kami, Kami yakin masih banyak kekurangan dalam makalah ini, Oleh karena itu kami sangat mengharapkan saran dan kritik yang membangun dari pembaca demi kesempurnaan artikel ini. Depth of field is one of the fundamental aspects that every photographer should understand as it has such a large bearing on your images. Depth of field determines how much of your image is sharp, giving you control — whether for creative or practical reasons — over which elements are in focus. Do you want to ensure that all of your photograph is crisp, from the foreground to the background, to ensure that there are no blurry parts that distract the viewer? Or do you want to make your image feel more cinematic, isolating your subject by making it stand out against a blurry background? This guide will help you to understand how to achieve both of these results, but more importantly, give you a solid foundation for how to use depth of field in every aspect of your photography. All of the common questions about depth of field asked by photographers will be addressed and although this can be a highly complex subject, we’ll aim to make it as digestible as possible. So grab a copy of this f-stop chart, find out what a camera f-Stop is, and follow along to improve your photography by mastering DOF.

In photography, the term depth of field describes the region of a photograph that is in focus. “In focus” is a relative term and given how easily how parts of an image can slide from being sharp to being blurry, what you might class as being “in focus” might vary according to how you are viewing an image — how big it is being displayed, and how close you are to it. Because of this, the depth of field can be thought of as being a range of acceptable focus. If you imagine yourself focusing on your subject. Everything that is the same distance away from your lens as your subject is now on the same focal plane. In addition to this, there will be a region in front of and behind the subject that is acceptably sharp. The full extent of this range is your depth of field. As will be discussed below, this depth of field can vary according to a number of variables such as how close you are to your subject, the size of your aperture, the focal length of the lens that you are using, and the size of the sensor in the camera which you are shooting on although these last two quickly get complicated!. Photographers are often trying to achieve one of two extremes a shallow or narrow depth of field, or a deep or wide depth of field. A shallow depth of field shallow DOF’ produces images where there is very little in focus other than the subject. Anything in front or behind the subject quickly becomes blurry. A shallow depth of field can be a way of creating images with a cinematic feel where a sharp subject is separated from a blurry background. This can help to direct a viewer’s attention and prevent other parts of the scene from being distracting. At the other extreme is a deep depth of field where the photographer maximises the region that is in focus, both in front of and behind the subject. Everything is sharp, whether it is just in front of the lens or on the horizon. A deep depth of field can be useful where you have a number of subjects that are all different distances from the camera and each of them needs to be in focus. This avoids making parts of the image out of focus which might undermine the quality of the photo as a whole.

The effect gives the image a three-dimensional feel. Sony a7 III + 7artisans 35mm f/ 1/800, f/ ISO 100 Photographing forests can be very chaotic and using a shallow depth of field allows the viewer to see the detail in the nearest tree without the rest of the image competing for the viewer’s attention by being equally sharp. It also creates a sense of depth and helps to emphasise the slight haze of the morning, both of which add a sense of mystery. Sony a7 III + 7artisans 35mm f/ 1/250, f/ ISO 4000 This photograph of a rock climber tackling an overhanging boulder uses an incredibly shallow depth of field to create a loose and abstract feel. Little of the image is in focus which isn’t of great importance as this image is about capturing a moment. The wide aperture also helped to photograph movement in very dark conditions by letting as much light as possible reach the sensor. 3 Deep Depth of Field Examples Sony a7 III + Sigma 65mm f/2 DG DN 1/400, f/10, ISO 100. Although the subject of this image is the person standing on the railing, this photograph also wanted to convey the context. Using a deep depth of field brings some sharpness to the mountains in the background in an attempt to convey some of the relationship between the foreground and the background. Sony a7 III + Canon 16-35mm f/ at 24mm. 1/1000, f/ ISO 5000. There are two subjects in this scene and one is much further away from the camera than the other. A deep depth of field ensures that both are in focus. In addition, this is also an environmental portrait and the location plays a major role in this photograph. Canon 6D + 16-35mm f/ at 16mm 1/320, f/8, ISO 1000. This image wants to communicate the texture of the concrete as well as the sense of perspective. The deep depth of field ensures that the texture of the steps in the foreground is felt but keeps all of the architecture sharp and in focus. How Do You Calculate Depth of Field? There are four variables that affect the depth of field. Two of these variables have a direct impact the distance between you and your subject subject distance’, and the aperture of your lens. Technically, it’s actually the entrance pupil of the lens which is something slightly different, but let’s worry about these finer details another time! There are then two other factors that play a role in understanding depth of field focal length and sensor size. The Distance Between You and Your Subject You may have noticed that when you focus your lens on the horizon, almost everything in the frame appears sharp. Equally, if you focus on something that’s just in front of you, everything behind it goes blurry. This is because the distance between you and the subject you are focusing upon affects how much of the scene in front of you is in focus. It’s useful to use a diagram in order to understand the behaviour of light when it enters a lens. When a lens focuses on a subject, it converges light rays to a point, and it is at this point of convergence — the focal plane mentioned above — where images are sharp. As you will recall, there is a region on either side of this focal plane where the image is acceptably sharp — our range of acceptable focus — that creates our depth of field. If the subject moves closer to the lens, these beams of light have to converge more sharply in order to be in focus, reducing the region within the image that is acceptably sharp, and giving a shallower depth of field In short, the closer you are to your subject, the shallower your depth of field. The further you are from your subject, the deeper your depth of field. The Size of your Aperture The aperture is the hole in your lens that let’s light pass through, one of two factors the other being shutter speed that determines the amount of light that reaches your sensor. The bigger the hole, the more light you let through. The size of this hole is described by a number that, thanks to a mathematical formula that we don’t need to worry about right now, gets smaller when the aperture gets larger. The higher the number, the smaller the aperture. The size of the aperture has a direct impact on the size of your depth of field. The bigger the aperture the smaller the number, the shallower the depth of field. The smaller the aperture the bigger the number, the deeper your depth of field. If we use the same diagram, you can see how this works. Here is a large aperture giving a shallow depth of field And below is a smaller aperture, giving a deep depth of field If you want to get as much of your scene in focus as possible, use a small aperture high number, f/11, f/16. If you want a sharp subject against a blurry background, use a large aperture low number, eg, f/ f/ The Focal Length of your Lens Focal length is described in millimetres. The higher the number, the narrower the field of view, and the closer distant subjects appear. When it comes to separating a subject from the background, a lens with a longer focal length will give a blurrier background and it’s true that they give a shallower depth of field — but not for the reasons that many photographers think. In the example below, it’s clear that the image on the right shot on an 85mm lens at f/ has a much blurrier background than the image on the left, shot on a 35mm lens, also at f/ The lens with the longer focal length has a much shallower depth of field. You can use a Depth of Field calculator see below to understand the difference I was shooting from a distance of 1 m, and at f/ the 35mm lens has a depth of field of cm. By contrast, the 85mm lens at this distance has a depth of field of cm. That’s a huge difference. But there’s another big difference between the two photos the size of the subject. What happens if the subject is made to appear the same size in each shot? To create this comparison, I moved further back and took another photograph using the 85mm lens. From m away — the distance I need to be to make the subject the same size in both images — my depth of field is 8 cm. Suddenly, the depth of field with both the 35mm lens and the 85mm lens shooting at f/ is almost identical. As you can see this has an effect the difference in blurriness is not as pronounced. The big difference is that the longer lens brings the background closer due to distance compression, and gives the impression that the background is more blurred because it is being magnified. So longer lenses do create a shallower depth of field, but the reasons behind it are more complicated than most photographers realise! Imagine this scenario you take a portrait of a person but when you review your photograph, you realise that the 35mm lens attached to your camera isn’t giving you the background separation that you want, even at the largest possible aperture of f/ Instead, you decide to use a longer focal length so you switch to your 85mm lens and recompose. Because of the longer focal length, you need to move back in order to create the same composition. If you keep the subject the same size in your frame between the two photos, your depth of field will be pretty much identical. However, the 85mm lens will give a blurrier background — and therefore more separation — because of compression, and not because the longer focal length gives you a shallower depth of field. Sensor Size Photographers often assume that using a camera with a smaller sensor automatically means a shallower depth of field but the reality is more complicated than that. As an example, consider the difference between a full-frame and an APS-C sensor. The APS-C sensor is physically smaller than the full-frame sensor and introduces crop factor as a result. This means that a lens used on a full-frame camera will give a narrower field of view when used on an APS-C camera. As a result, if you are photographing a subject and switch from a full-frame camera to an APS-C camera, you will need to move further back in order for your subject to be the same size in your frame. As explained above, moving further away from your subject creates a deeper depth of field. Doing the Math There is a mathematical formula that combines the f-number of the lens, its focal length, the distance to the subject that gives the depth of field of a lens. This formula also includes something called the circle of confusion which is a figure given to a lens that describes how big a single point of light becomes before it is no longer acceptably sharp. Circle of confusion is a confusing topic !, but we do our best to explain it in this guide. The formula above allows us to calculate precisely the depth of field from any given focal length, distance to subject, and aperture. Notice that sensor size isn’t included in this equation. A 50mm lens is a 50mm lens regardless of whether you use it on a full-frame camera or an APS-C camera. However, on an APS-C camera, your field of view will be narrower. Depth of Field Calculator Here’s a useful way to calculate the depth of field based on your camera and the factors above. Hyperfocal distance the focusing distance that gives your photos the greatest depth of field. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance through to infinity will be acceptably sharp. Hyperfocal near limit The distance between the camera and the first element that is considered to be acceptably sharp when focusing at the hyperfocal distance. Depth of field DOF The distance between the furthest and closest points that are in acceptable focus the zone of acceptable sharpness in front of and behind the subject to which the lens is focused on. DOF near limit The distance between the camera and the first element considered to be acceptably sharp. DOF far limit The distance between the camera and the furthest element considered to be acceptably sharp. Depth of Field DOF In Front Distance between the DoF Near Limit and the focus plane. Depth of Field DOF Behind Distance between the focus plane and the DoF Far Limit. Thanks to PhotoPills for the tool and definitions. Depth of Field Chart The chart above shows the effects on depth of field that changes in lens aperture produce. As the f-number of the lens increases, the greater the depth of field. As the f-number decreases, the shallower the depth of field. Click the image to view it larger, then print it out and use it as a depth of field cheat sheet next time you’re out taking photos. Depth of Field FAQs What f-stop gives the greatest depth of field? The f-stop is used to describe the size of the aperture in your lens. The lower the number, the bigger the aperture, and the shallower the depth of field. The higher the number, the smaller the aperture, and the deeper the depth of field. Does depth of field increase performance? Lenses tend to be sharpest when they are not used at one extreme or another. Wide open with a shallow depth of field, they can lose sharpness and suffer from other aberrations. At their smallest aperture with a deep depth of field, images can be soft as a result of diffraction. What is a minimum depth of field? Minimum depth of field describes the shallowest depth of field that can be produced by a lens. This is achieved by setting the lens to its maximum aperture. How do you maximize depth of field? To maximize depth of field, decrease the size of your aperture or move further away from the subject you are focusing upon. Alternatively, without moving, switch to a lens which has a shorter wider focal length. How does distance affect depth of field? As you get closer to the subject you are focusing upon, depth of field becomes shallower and out-of-focus areas become more blurry. Which lens is best for depth of field? To achieve the shallowest depth of field, choose a lens with a large maximum aperture. A great place to start is a 50mm f/ lens as it is small, lightweight, and very affordable. If you have the money, try a 50mm f/ or even an f/ lens! What is a high depth of field? Depth of field can either be shallow narrow or deep wide. A depth of field cannot be high, but you may wish to use an aperture with a high number in order to create a deep depth of field. When would you use depth of field? You might use a deep depth of field when photographing a landscape to ensure that the image is as sharp as possible from the front of the image to the back, and no part distracts the viewer by being blurred. Alternatively, you may use a shallow depth of field when photographing a portrait in order to blur the background and direct the viewer’s attention to your subject. Does shutter speed affect depth of field? Shutter speed does not affect depth of field. However, if you are trying to create a deep depth of field by using a small aperture, you will need to reduce your shutter speed and ISO in order to ensure the correct exposure. Does ISO affect depth of field? ISO does not affect depth of field. However, making your aperture smaller to give a deeper depth of field, or larger to create a shallow depth of field will require you to change your ISO and shutter speed in order to expose correctly. Which f-stop is sharpest? Typically, the sharpest f-stops on a lens are two or three stops smaller than the largest possible aperture. For example, a lens with a maximum aperture of f/ will often be sharpest when used between f/ and f/8. Understanding Depth of Field Final Words Depth of field can be confusing at first but it’s worth gaining a good understanding as it will have a huge impact as you progress with your photography. Understanding depth of field will help you make sure the focus in your photographs is exactly where you need it, whether it’s complete sharpness from the front to the back of an image, a razor-thin depth of field that separates your subject, or something in between. The important elements to note are that getting close to your subject and using a larger aperture will give you a shallower depth of field. Using a longer lens will also create a shallower depth of field unless you also have to move away from your subject in order to accommodate it, in which case it will just give the impression of a shallower depth of field because of distance compression. It’s quite a lot to take in but if you have any questions, be sure to leave a comment below.

Learn more here Image Credit Flickr Cara obyek direproduksi dalam sebuah foto bisa sangat berbeda dari bagaimana ia tampil ketika diambil gambarnya. Ketika Anda menatap dengan mata Anda ke seluruh obyek, segala sesuatu di dalamnya tampak kurang lebih sama tajam, tapi kadang-kadang hanya fokus bagian tertentu obyek foto sehingga tampak tajam dan tampak blur di bagian selainnya. Disini akan kita bahasa penjelasan mengenai DOF. Zona ketajaman ini disebut depth-of-field DOF, yaitu ketajaman yang membentang ke depan dan ke belakang dari titik yang benar-benar menjadi fokus pada saat itu. Ukuran zona ketajaman ditentukan oleh tiga faktor utama – aperture atau bukaan lensa, panjang fokus lensa dan jarak Anda dari subjek. Memvariasikan ketiga elemen ini memungkinkan Anda mengontrol hampir penuh atas hasil depth-of-field dalam foto/gambar. Ilustrasi Depth of Field area ketajaman Ketika sebagian besar bagian obyek pada gambar terlihat tajam, maka kita katakan DOF luas. Bila hanya beberapa bagian saja yang tajam, maka kita katakan DOF sempit atau terbatas. Apakah kita akan menggunakan depth-of-field luas atau sempit tergantung pada konsep dan bagaimana ingin menggambarkan obyek terkait. Tiga faktor utama yang dapat digunakan untuk mengontrol DOF. Faktor Utama Penentu DOF 1. Aperture Lensa Hubungan langsung antara aperture dan depth-of-field yaitu semakin kecil aperture, semakin luas depth-of-field artinya semakin banyak bagian yang tajam dan sebaliknya, semakin besar aperture semakin sempit depth-of-field semakin sedikit bagian yang tajam. Jadi jika Anda ingin mendapatkan sebanyak mungkin bagian foto yang tajam, setting sekecil mungkin aperture – misal antara f/16, atau bahkan f/22 jika lensa mendukung. Jangan lupakan kondisi pencahayaan, mungkin perlu menggunakan tripod atau bentuk lain yang membuat kamera stabil karena dengan aperture kecil kecepatan shutter membutuhkan lebih lama sehingga menciptakan risiko hasil foto blur karena kamera-goyang. Namun, jika Anda ingin memusatkan perhatian hanya pada satu bagian dari obyek foto, dan membuang sisanya agar blur/out-of-focus, sebaiknya pilih aperture besar. Seberapa besar persisnya ini bisa tergantung pada aperture maksimum lensa yang Anda gunakan. Pada lensa standar 50mm bisa f/1,7 f/1,8 atau f/2, tetapi untuk standar biasanya sekitar f/3,5 atau f / 4,5. Untuk pengambilan gambar pada umumnya, bila Anda ingin sebagian besar bagian foto tajam, Anda bisa mengatur aperture sekitar f/8 sampai f/11. Ini bisa dicapai dengan setting mode eksposur Program dimana akan diatur secara otomatis oleh kamera. Bila memungkinkan Anda harus mengambil kendali seleksi aperture dan menggunakan Aperture-Priority atau mode manual. Berikut adalah contoh bagaimana menggunakan lensa Nikon lama untuk membantu menunjukkan skala dan kedalaman lapangan berdasarkan aperture yang dipilih. Lensa diatur ke aperture f/8, segala obyek dari jarak infinity simbol yang terlihat seperti angka delapan ke jarak 5kaki akan tampak tajam. Lensa diatur ke aperture f/22, segala obyek dari jarak infinity simbol yang terlihat seperti angka delapan ke jarak 2 kaki akan tampak tajam. 2. Panjang Fokus Lensa Menggunakan lensa wide-angle Anda akan mendapatkan keuntungan dari depth-of-field yang luas, yang membuatnya mudah untuk menjaga semua bagian obyek dalam foto dalam fokus. Semakin lebar sudut view, semakin besar dept-of-field. Sebaliknya jika menggunakan lensa tele maka depth-of-field lebih terbatas. Semakin besar focal-length lensa tele, semakin membatasi zona ketajaman. Sebagai contoh pengaruh menggunakan focal length yang berbeda adalah. Lensa Nikon 28mm wide-angle di f/22 akan memberikan hasil yang tajam dari jarak 2 kaki hingga jarak infinity tak terbatas. Sedangkan lensa Micro Nikkor 55mm dari jarak 7 kaki hingga infinity. Dan lensa Nikkor 105mm dari jarak sekitar 28 meter hingga tak terbatas. 3. Jarak Kamera ke Obyek Semakin dekat kamera dengan obyek foto maka semaki terbatas depth-of-field atau ruang ketajaman. Bahkan, saat pengambilan foto close-up atau macro maka ruang ketajaman akan menjadi sangat sempit hanya beberapa milimeter di depan dan di belakang obyek. Jadi di atas adalah penjelasan secara teorinya, perlu banyak berlatih praktek langsung sekian lama untuk mendapatkan feel mengenai DOF ini. Bersambung ke Bagian-2 yaitu contoh teknik umum menggunakan depth-of-field Bagian Kedua source Author Recent Posts A writer and photographer with a passion for technology, astronomy, and virtual reality. Skilled in multiple programming languages, specializing in software architecture. Depth of field control is a key attribute of image quality that helps DSLRs and mirrorless cameras stand above pont-and-shoots. Shallow depth of field, the effect that allows you to have a tack-sharp subject against a blurry background, is such a sought-after look that smartphones try to emulate it using multiple lenses and computational photography. But what really is depth of field, and how do you control it? Deep versus shallow depth of field Put simply, depth of field refers to how much depth in your image is in focus. If objects both close to and far away from he camera are sharp, then you have a deep depth of field. If the foreground or background is blurred, you have a shallow depth of field. A popular analogy here is a swimming pool At its deepest, there will be more water. Likewise, a deep depth of field means more of the image is in focus. An example of when to use a deep depth of field could be a landscape, where the entire image is essentially the subject. This is particularly true if there are both foreground and background elements that you want to keep in focus, as in the following photo Download full resolution Shallow depth of field is useful for the opposite, when you have a single subject that you want to isolate from what is in front or behind it. This is commonly used in portraiture and can be especially useful if you have a busy, distracting background. A wide fast aperture is used to separate a subject from the background. Daven Mathies/Digital Trends The dictionary definition of depth of field is adds a word to our above description, calling it the distance between the nearest and farthest points of acceptable focus. Seems simple enough, but you may be wondering to yourself right now — what is acceptable focus? Acceptable focus is based around the circle of confusion and some other advanced topics, but it basically comes down to what looks to be in focus to your eyes. Technically, a camera’s lens can only focus on a single plane in space, like one slice of bread in a loaf. Everything in front and behind that plane falls is out of focus, or defocused. However, our eyes can only see so much detail, including blur detail. If a point of blur is too small for our eyes to detect, then that area will appear to be in focus. This quick video from Adorama is a great primer on the circle of confusion and acceptable focus. The Circle of Confusion Exploring Photography with Mark Wallace AdoramaTV Depth of field is determined by the relationship of the aperture f-stop and focal length of your lens, the distance of the subject in the photo, and the size format of the sensor. The most common way to change your depth of field is by adjusting the aperture of your lens, which determines how much light your lens allows through it and on to your camera sensor. The narrower the aperture is, the deeper the depth of field. A wide open aperture creates nicely soft backgrounds with a shallow depth of field. Here, the depth of field is sometimes so narrow that your subject’s eye could be in focus but the tips of the eyelashes may be soft. These wide apertures like f/ or f/2 draw more attention to the subject by blurring out the background, but larger or close-up subjects may not be entirely in focus. On the other hand, a narrow aperture such as f/11 or f/16, keeps more of the image in focus. A small aperture is often recommended for landscape photography because you may need to maintain sharpness from very close foreground elements all the way out to distant elements like skylines or sunsets. You may have noticed that smartphones often have bright lenses with seemingly wide apertures, like f/ on the iPhone 11 Pro — and yet, the depth of field is still very long. Why? This is because sensor size also plays a role in the depth of field. The technical explanation behind this is a bit, well, technical, but the takeaway is this The larger the sensor, the easier it is to get those nice soft backgrounds. But a large sensor requires a much bigger lens, which simply wouldn’t fit in in a phone. Smartphones can, however, imitate a blurred background using software, the results of which can be impressively realistic in the right situations, and even allow you to change the depth of field after the fact. However, computational portrait modes still fail in many instances and don’t always work with every type of subject, such as ones that are too close or too far away. Remember, though, that depth of field is the range of distance that appears acceptably sharp. That means if you’re shooting at your widest aperture with a large sensor camera and the background still isn’t blurry enough, there’s still more that you can do. Move the subject farther away from the background, and that background will appear softer without changing any camera settings. In a similar manner, the closer the camera is to the subject, the softer the background appears. Macro photographs are often shot at smaller apertures, even when that soft background is desired, because the camera is so close to the subject that the depth of field is shallow regardless of aperture. Some macro photographers even use focus stacking to get more depth of field, which involves taking several exposures at different focus distances and merging them together in an editing program for a sharper shot. Telephoto lenses also create a shallower depth of field compared to wide-angle lenses. This is one reason why telephoto lenses are often preferred for portraiture, while wide-angles are used in landscapes. Of course, like everything in photography, this is not a hard and fast rule. Conclusion While the math that explains depth of field is complex, the techniques to control it are not. To create a softer background, use a wider aperture lower f-number, use a large-sensor camera, move closer to the subject, or move the subject farther from the background — or maximize the effect with a combination of all those factors. For sharper images with more details intact, use a narrower aperture, move farther from the subject, or move the subject closer to the background.
